CONVEYE R FOR SMOKE AND 'CINDERS.

SPBCIFICATIQN forming part of Letters Patent No. 290,586, dated December 18, 1883.

Application filed August 2. 1883. (No model.)

To LZZZ whom, it may concern.-

Be it known that I, LEwIs G. JOHNSON, a citizen of the United States, residing at Auburn, in the county of Logan and State of Kentucky, have invented certain new and useful Improvements in Gonvcyers for Smoke and Cinders; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in conveyers for smoke and cinders, and has for its objects to convey the smoke and cinders from a locolnotiveengine over the tops of the cars, and to discharge the same in the rear thereof, thus preventing the discomfort incident to railroad travel. These objects are attained by the mechanism illustrated in the accompanying drawings, forming a part of this specification, in which Figure l is a side elevation. tailed sectional view of coupling. Fig. 3 is a view of one of the pipes removed. Fig. 4 is a sectional View of a part of one of the flexible connections. Fig. 5 is an end view of one of the couplings, showing the manner of ap- Fig. 2 is a deplying the wrench to form or break the connection.

The letter A indicates a metallic cap,which is made of proper size and shape to fit over the smoke-stack of the engine.

From the cap A. there extends in an upward and backward direction a curved pipe or elbow, B, thence horizontal, B, and terminating in a coupling, 0, at or about the after end of the engine or tender. The pipe B is slightly enlarged at the end, or is provided -with a channel or groove, 1), adapted to receive the 'point of a set-screw, e. The coupling is composed of a metal band, 0, adapted to fit over the end of the pipe B, upon which it turns freely. As the point'of the screwe fits into the groove b, the pipe B and the band 0 are thereby connected to each other. The outer end of the band C is cut with a female screw, which engages with a screw out on the end of a band, C, attached to a flexible tube, D, which extends from the engine or tender to the next car, and is there coupled in a similar manner to the metal tube B, each end of which is provided with metal bands 0, similar in construction to G, already described.

F is the Smokestack of the engine. Each car in the train is provided with a metal tube extending from one end of the car to the other, over the roof, constructed in every particular in the same manner as B, and the space be tween each tube B is occupied by a flexible connecting-tube similar in all respects to the tube 1), so that a continuous line of tubing extends from the smoke-stack of the engine to the rear of the last car in the train, whereby the smoke and'cinders maybe carried and discharged at the desired point.

The bands G C have projecting pins 6, over which a wrench is fitted and used in making or changing the connections, as the couplings, when made in the manner already described, permit the tube D to be turned in either di rection without twisting after the couplings G C O are firmly screwed together.

The pins 6 may be attached to the bands 0 G by screw-threads, and made to serve as setscrews to firmly fasten the bands to the pipes B B B, and prevent said bands from working loose.

The flexible tubes I prefer to make of rubher, and, in order to prevent their being burned by the cinders, I line them on the inside with a close spiral of wire, as shown in Fig. 5, letter L, thus forming a metallic covering to the rubber, which is at the same time I The conducting-pipes B B may be connected to the tops of the cars by any suitable sup ports.

Having described my invention, what I I DO claim, and desire to secure by Letters Patent, In testimony whereof I affix my signature in isv presence of two witnesses.
